Best money I have spent. This fin has allowed me to paddle where I thought was not possible giving me the best joy, battery life is phenomenal.
One bonus that I did not consider when purchasing is I work with disabilities so now I get to teach people with disabilities how to paddle as this fin is the back up plan for if they become tired or unable to paddle. This product has opened so many doors and to be able to give these people the opportunity to take part in a sport that they thought was unobtainable is priceless I will be buying another one

Boost Fin
Great product. Have adjusted the settings to suit. Only small problem was a retaining bolt holding one of the propellor fins on undid itself almost completely. I put put locktight on all of them and to date have no further problems. The unit is very good in its operation.
